Design of narrowband infrared emitters by hybridizing guided-mode resonance structures with van der Waals materials
Mehrdad Shokooh-Saremi, Maxime Giteau, Mitradeep Sarkar +1
In this paper, narrowband emitters have been designed using particle swarm optimization (PSO) in the 10-20 μm infrared range. The device structure consists of an anisotropic α-MoO3…

Deep-subwavelength Phase Retarders at Mid-Infrared Frequencies with van der Waals Flakes
Michael T. Enders, Mitradeep Sarkar, Aleksandra Deeva +5
Phase retardation is a cornerstone of modern optics, yet, at mid-infrared (mid-IR) frequencies, it remains a major challenge due to the scarcity of simultaneously transparent and b…

Retrieving optical parameters of emerging van der Waals flakes
Mitradeep Sarkar, Michael T. Enders, Mehrdad Shokooh-Saremi +5
High-quality low-dimensional layered and van der Waals materials are typically exfoliated, with sample cross sectional areas on the order of tens to hundreds of microns. The small…
